Subject: [RFC PATCH 0/8] Fix perf probe issues on powerpc
Date: Tue, 9 Dec 2014 23:03:58 +0530 [thread overview]
Message-ID: <cover.1418146300.git.naveen.n.rao@linux.vnet.ibm.com> (raw)
This patchset fixes various issues with perf probe on powerpc
across ABIv1 and ABIv2:
- in the presence of DWARF debug-info,
- in the absence of DWARF, but with the symbol table, and
- in the absence of debug-info, but with kallsyms.
Applies cleanly on v3.18 and on -tip with minor changes to patch 6.
Tested on ppc64 BE and LE.

Naveen N. Rao (8):
kprobes: Fix kallsyms lookup across powerpc ABIv1 and ABIv2
perf probe powerpc: Fix symbol fixup issues due to ELF type
perf probe: Improve detection of file/function name in the probe
pattern
perf probe powerpc: Handle powerpc dot symbols
perf probe powerpc: Allow matching against dot symbols
perf tools powerpc: Fix PPC64 ELF ABIv2 symbol decoding
perf probe powerpc: Use DWARF info only if necessary
perf probe powerpc: Fixup function entry if using kallsyms lookup
